Description

Technical Field

[0001] This utility model relates to the field of cardboard production technology, and in particular to a binding device for cardboard packaging. Background Technology

[0002] Packaging boxes are mainly made of folded cardboard. According to actual needs, the cardboard is first cut into the required size, then printed, grooved, and nailed. After that, multiple finished products need to be stacked together for packaging. For packaging cardboard, it is essential to position it accurately, press it tightly, and then pack it.

[0003] Existing devices are mostly complex in structure, and some require manual operation to move the pressing plate downwards to press the cardboard, which is time-consuming and laborious and cannot meet more needs.

[0004] An existing patent (publication number: CN215972275U) discloses a binding device for packaging cardboard production, including a first pressure plate and a second pressure plate. The tops of both the first and second pressure plates are symmetrically provided with guide grooves, each containing a compression spring. Hydraulic cylinders are fixedly mounted on both the first and second pressure plates, with a pressure rod fixed between the output ends of the hydraulic cylinders. A pressure plate is fixedly mounted at the bottom end of the pressure rod. The tops of both the first and second pressure plates are symmetrically provided with locking slots containing straps. The operator first pulls a stop bar and stacks the cardboard pieces under the pressure plate. Then, the stop bar is released, and the pressure springs clamp the cardboard, preventing misalignment. Next, the hydraulic cylinders are activated, causing the pressure rods to move downwards, which in turn moves the pressure plate downwards, compressing the cardboard. Finally, the compressed cardboard is bound with straps. The device is lightweight, time-saving, and labor-saving.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, most existing devices cannot control the optimal clamping force based on the characteristics of the cardboard when pressing stacked cardboard. Furthermore, during the pressing process, excessive speed or force may easily cause damage and deformation to the cardboard. Moreover, during the binding process, most devices can only bind from both sides, making it difficult to adapt to higher binding requirements.

[0006] Therefore, a binding device for cardboard packaging is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5The present invention provides the following technical solution:

[0028] A binding device for cardboard packaging includes a base plate 1, with support rods 2 bolted to the four corners of the top of the base plate 1, and a worktable 3 bolted between the tops of the four support rods 2. The top of the worktable 3 is respectively provided with a rotating placement component 4 and a flexible pressing component 5.

[0029] The flexible clamping assembly 5 includes a mounting frame 51, the bottom of which is bolted to the top of the workbench 3. A first telescopic electric cylinder 52 is installed inside the top of the mounting frame 51. A connecting sleeve 53 is fitted on the bottom of the first telescopic electric cylinder 52. A pressure sensor 54 is bolted to the bottom of the inner wall of the connecting sleeve 53. A spring 55 is connected to the top of the pressure sensor 54. The top of the spring 55 contacts the bottom of the first telescopic electric cylinder 52. A clamping plate 56 is bolted to the bottom of the connecting sleeve 53.

[0030] In this embodiment: First, the cardboard to be bundled is placed on the rotating placement assembly 4 of the workbench 3. Then, the flexible pressing assembly 5 is activated, and the first telescopic electric cylinder 52 at the top of the mounting frame 51 starts working and extends downward. The connecting sleeve 53 moves down with the first telescopic electric cylinder 52, driving the pressing plate 56 at the bottom to approach the cardboard. When the pressing plate 56 contacts the cardboard, during the continued pressing process, the pressure sensor 54 will collect the reaction force generated by the cardboard on the pressing plate 56. As the first telescopic electric cylinder 52 continues to press down, the spring 55 is compressed, and the pressure sensor 54 will provide real-time feedback of the collected pressure data. When the pressure reaches the preset value, the first telescopic electric cylinder 52 stops moving. At this time, the pressing plate 56 flexibly presses the cardboard under the buffering effect of the spring 55, avoiding damage to the cardboard and preparing for the subsequent bundling operation. After bundling, the rotating placement assembly 4 can be activated to rotate and change the sides, realizing multi-directional bundling of the cardboard and achieving higher bundling requirements.

[0031] Specifically, such as Figure 1 , Figure 3 As shown, the rotating placement assembly 4 includes a support column 41, the bottom of which is bolted to the top of the worktable 3.

[0032] Specifically, such as Figure 3 As shown, a rotating cap 42 is fitted on the top of the support column 41, and a placement plate 43 is bolted to the top of the rotating cap 42.

[0033] Specifically, such as Figure 3 As shown, a first gear 44 is fitted on the surface of the rotating cap 42, a first motor 45 is bolted to the top of the workbench 3, and a second gear 46 is fitted on the surface of the output shaft of the first motor 45, and the second gear 46 meshes with the first gear 44.

[0034] In this embodiment: After the cardboard is placed, the operator issues a command through the controller 8 to start the first motor 45 in the rotating placement assembly 4. The output shaft of the first motor 45 starts to rotate. Since the surface of the output shaft of the first motor 45 is fitted with a second gear 46, the second gear 46 rotates accordingly. The first gear 44 fitted on the surface of the rotating cap 42 meshes with the second gear 46. The rotation of the second gear 46 drives the first gear 44 to rotate, thereby causing the rotating cap 42 to start to rotate. The top of the rotating cap 42 is bolted with a placement tray 43, so the placement tray 43 also rotates. The cardboard placed on the placement tray 43 rotates accordingly. In this way, the cardboard can be rotated to change sides, so as to achieve more comprehensive binding in the subsequent binding process and meet higher binding requirements. For example, after one side of the cardboard is bound, the placement tray 43 is rotated to make the other side of the cardboard face the appropriate position for binding.

[0035] Specifically, such as Figure 2 As shown, limit grooves 6 are provided at the bottom of both sides of the first telescopic electric cylinder 52, and guide bars 7 are provided inside the connecting sleeve 53. The limit grooves 6 and guide bars 7 are used together.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a controller 8 is bolted to the front of the top of the mounting bracket 51, a rubber pad 9 is bolted to the bottom of the clamping plate 56, and a rope roll 10 is provided on the right side of the rear of the top of the workbench 3.

[0037] In this embodiment: After the cardboard is placed, the controller 8 controls the first telescopic electric cylinder 52 of the flexible pressing assembly 5 to start working. The first telescopic electric cylinder 52 extends downward. Since the bottom of both sides of the first telescopic electric cylinder 52 has limit grooves 6, the guide strip 7 inside the connecting sleeve 53 cooperates with the limit grooves 6 to ensure that the connecting sleeve 53 can only move downward along the axial direction of the first telescopic electric cylinder 52 and will not rotate. The bottom of the connecting sleeve 53 is bolted with a pressing plate 56. As the connecting sleeve 53 moves downward, the pressing plate 56 also moves downward. The bottom of the pressing plate 56 is bolted with a rubber pad 9. When the rubber pad 9 contacts the cardboard on the placement tray 43... Pressure is applied to the cardboard. During the pressing process, the pressure sensor 54 at the bottom of the inner wall of the connecting sleeve 53 monitors the pressure in real time. The pressure sensor 54 transmits the pressure signal to the controller 8 bolted to the front top of the mounting frame 51. When the pressure reaches the preset value, the controller 8 controls the first telescopic cylinder 52 to stop extending to avoid excessive pressure that could damage the cardboard. The spring 55 and the rubber pad 9 act as a buffer and provide soft contact during this process to prevent sudden pressure changes and hard contact from damaging the cardboard. At the same time, the operator can take out the binding rope from the binding rope roll 10 located on the right side of the rear top of the workbench 3 to bind the pressed cardboard.

[0038] Specifically, such as Figure 4 , Figure 5 As shown, a second telescopic electric cylinder 11 is bolted to the top of the substrate 1, a first horizontal block 12 is bolted to the top of the second telescopic electric cylinder 11, a second horizontal block 13 is bolted to the top of the first horizontal block 12, and a sliding groove 14 is provided inside the first horizontal block 12 and the second horizontal block 13. Two sliders 15 are slidably arranged inside the sliding groove 14, and an alignment push rod 16 is bolted to the opposite side of the two sliders 15.

[0039] Specifically, such as Figure 5 As shown, the two sliders 15 are connected by a threaded screw 17. The two screws 17 are rotatably connected to the first horizontal block 12 and the second horizontal block 13 respectively. The rear side of the first horizontal block 12 and the left side of the second horizontal block 13 are both bolted to the second motor 18. The output shafts of the two second motors 18 extend into the corresponding first horizontal block 12 and the corresponding second horizontal block 13 and are bolted to the corresponding screws 17.

[0040] In this embodiment: When placing cardboard, the cardboard may not be neatly arranged. To make the cardboard neatly arranged and easy to bundle, the controller 8 controls the second telescopic electric cylinder 11 to work. The second telescopic electric cylinder 11 extends upward, driving the first horizontal block 12 and the second horizontal block 13, which are bolted to the top of the first horizontal block 12, to move upward, adjusting the alignment push rod 16 to a suitable height. Then, the controller 8 starts the second motor 18, which is bolted to the rear of the first horizontal block 12 and the left side of the second horizontal block 13. The output shaft of the second motor 18 rotates, driving the positive and negative threaded screw 17 bolted to it to rotate. Since the two sliders 15 are internally connected by a threaded rod 17, the rotation of the threaded rod 17 causes the two sliders 15 to move relative to each other in the sliding grooves 14 opened inside the first horizontal block 12 and the second horizontal block 13. Alignment push rods 16 are bolted to the opposite side of the two sliders 15. The relative movement of the sliders 15 drives the alignment push rods 16 to move towards the middle, thereby pushing the cardboard on the placement tray 43 to make the cardboard neatly arranged. After the cardboard is aligned, the controller 8 controls the second motor 18 to reverse, so that the alignment push rods 16 return to the initial position, preparing for the subsequent binding operation.

[0041] Working principle: The operator places the cardboard to be bundled on the placement tray 43 of the rotating placement component 4 on the workbench 3. If the cardboard is not neatly arranged, the controller 8 controls the second telescopic electric cylinder 11 to extend upward, driving the first horizontal block 12 and the second horizontal block 13 to rise, adjusting the alignment push rod 16 to the appropriate height. Then, the second motor 18 behind the first horizontal block 12 and the second horizontal block 13 is started. Its output shaft drives the positive and negative threaded rods 17 to rotate, causing the two sliders 15 to move relative to each other in the sliding groove 14, driving the alignment push rod 16 to move towards the center, pushing the cardboard to be neatly arranged. After the cardboard is aligned, the second motor 18 reverses to return the alignment push rod 16 to the initial position. After that, the controller 8 controls the first telescopic electric cylinder 52 of the flexible pressing component 5 to work, which extends downward. Because the bottom limiting grooves 6 on both sides of the first telescopic electric cylinder 52 cooperate with the guide strips 7 inside the connecting sleeve 53. The connecting sleeve 53 can only move downward along the axial direction without rotating. The connecting sleeve 53 drives the pressure plate 56 bolted to the bottom to move downward. After the rubber pad 9 at the bottom of the pressure plate 56 contacts the cardboard, it begins to apply pressure. The pressure sensor 54 at the bottom of the inner wall of the connecting sleeve 53 monitors the pressure in real time and transmits the signal to the controller 8. When the pressure reaches the preset value, the controller 8 controls the first telescopic electric cylinder 52 to stop extending. The spring 55 and the rubber pad 9 play a buffering and soft contact role to prevent damage to the cardboard. At this time, the operator can take out the binding rope from the binding rope roll 10 to bind the pressed cardboard. If it is necessary to rotate and change the surface to achieve multi-directional binding, the controller 8 issues a command to start the first motor 45 of the rotating placement component 4. Its output shaft drives the second gear 46 on the surface to rotate and mesh with the first gear 44 on the surface of the rotating cap 42, driving the rotating cap 42 and the placement plate 43 on the top to rotate, so that the cardboard rotates and changes the surface.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
